The math dragons have assembled! These three fearsome beasts represent the holy trinity of imaginary numbers in mathematics. On the left, we have the OG imaginary number i² = -1, the rebel that dared to be the square root of negative one. In the middle, j² = 1 (with j ≠ ±1) is that weird cousin who shows up at family gatherings with strange properties. And on the right, ε² = 0 (with ε ≠ 0) is basically the mathematical equivalent of existing but also not really mattering much.
This is what mathematicians see in their nightmares after spending too many hours trying to solve complex equations. The dragons aren't real... but then again, neither are imaginary numbers, and yet here we are, using them to build everything from electrical circuits to quantum mechanics. That's mathematics for you - making up numbers and then getting scared of them!
